摘　　要：为了实现星敏感器的地面标定试验,设计一套视场大且星间角距模拟精度高的星敏感器地面标定系统,对标定系统的组成、光学系统设计和模拟仿真精度等进行研究。根据星敏感器的地面标定要求介绍系统组成,提出实现星间角距模拟精度优于20″的方法;采用新型显示器件LCOS作为星图显示器,通过像面拼接的方法扩大视场,并据此利用Zemax软件设计光学系统。在原有测量方法的基础上,给出地面标定设备的精度评价方法。并提出一种能够提高星间角距模拟精度的星点修正方法。实验结果表明:星敏感器地面标定设备的星间角距模拟精度小于20″,满足对星敏感器进行地面标定试验的要求。In order to realize the ground calibration tests of star sensors, a ground calibration system of large field of view and high angular distance between stars’ simulation accuracy was designed, the composition of calibration system, optical system design and simulation precision were studied. According star sensors ground calibration requirements the system components was introduced, a method to realize the angular distance between stars’ simulation precision better than that of 20＇＇ was put forward. Using the new display LCOS as star chart display, the image plane field by splicing methods was expanded, and Zemax software was used to design the optical system accordingly. On the basis of the original measuring method, the evaluation method of ground calibration equipment precision was given. And a way was proposed to improve the angular distance between stars’ simulation accuracy by the method of star correction. The experimental results show that the star sensor ground calibration equipment of the angular distance between stars＇simulation precision is less than 20＇＇, meet the star sensor for ground calibration test requirements.
